Question

18 POINTS What is the surface area of this rectangular prisim

Answer 1

Answer:

Surface area of the rectangular prism = $88inch^2$

Step-by-step explanation:

Surface area of the Rectangular Prism:

2(Length*Width+ Width*Height+Height*Length)

Length=10 inch

Width=2 inch

Height= 2 inch

Surface area of the rectangular prism:

                                 $= 2((10*2)+(2*2)+(2*10))\\\\=2(20+4+20)\\\\=2(44)\\\\=88inch^2$

The surface area of the rectangular prism is $88inch^2$

Answer 2

Answer: 88 inches ^2

Step-by-step explanation:

Surface area of a rectangular prism is calculated by A=2(wl+hl+hw)

where w is width given as 10inches

h is the height given as 2inches

l is the length given as 2inches

wl = width x length = 10 x 2 = 20inches

hl = height x length= 2 x 2 = 4inches

hw= height x width = 2 x 10 = 20inches

Slot the values into the formula

A= 2 (20 + 4 + 20)

A= 2 (44)

A = 2 x 44

A = 88inches^2
